Safety and Extra Fittings

Tractors today are provided with roll-over protection systems known as ROPS. If the tractor overturns, the operator does not get crushed under it. In open air tractors the ROPS comprises of a steel beam over the driver's seat. In other models (operator cabs), ROPS is fixed to the frame of the vehicle. Previously, such incidents were quite common. In the tricycle design of yesteryears, the front wheels were placed close together and angled inward toward the ground. Usually, the accidents occurred while the tractor was trying to move along steep inclines. Accidents also occurred when the tractor tried to pull excessive loads. Another cause of accidents was the freezing of tires during winter. Legislation has been initiated to check the danger, but as an extra precaution, it is advisable to see that ROPS has been actually installed. There are many ways the unscrupulous manage to sideline the law to save a penny here and there.

With the help of a drawbar of a three point hitch, farm implements can be fixed to the back portion of the tractor. Equipment attached to this three point hitch can be raised or lowered by hydraulic power with the help of a control lever. Generally, the tractor completely supports the attachments of the three point hitch. Another way is to take the help of Quick-Hitch, which in turn is fixed to the three point hitch. This makes it possible for a single person to attach the implements quickly without taking any risks. When the tractor is used in large gardens and public parks, the tractor may require some additional fixtures and changers. Workers operating on the highway have blow-torch cylinders strapped to its sides. A pneumatic drill air compressor is permanently fixed over its power takeoff. Grass tires are fitted, causing less damage than agricultural tires to soft surfaces.
